Movie Theater Hires Ninjas To Stop Annoying Behavior

A theater in London has employed people to dress in black bodysuits and quiet down rowdy moviegoers. Do you think these "movie ninjas" need to make the trip overseas?

The disguised users work in exchange for free admission to the movie and target people who are doing all the stuff that that annoys you at the theater - talking on the phone, throwing popcorn, having a conversation and texting. I personally hate when someone does all of those things in a movie theater and am all for some stealth justice. I guess the only concern might be for the "ninjas" safety. What do you think? Would you like to see this employed in a theater near you?
